Roch, T. (author), Šimurka, L. (author), Ow-Yang, C.W. (author), Sezen, M. (author), Satrapinskyy, L. (author), Turutoğlu, T. (author)Magnetron sputtering is widely used for deposition of silicon oxynitride (SiOxNy) coatings on glass in large-area applications. Since repeated deposition simulates the factory-scale in-line processing, amorphous aluminum-doped SiOxNy layers with thickness of about 250 nm were deposited by reactive pulsed DC sputtering in a multi-pass process...article 2019

Reinders, J.E.A. (author), Velthuis, J.F.M. (author), Spruijt, M.P.N. (author)Damage caused by incidents with transport tanks with compressed liquified gas is amongst the most extreme that can be encountered with transport vessels. This is particularly the case with the Boiling Liquid Expanding Vapor Explosion (BLEVE), which may occur if such a tank is exposed to fire for a prolonged period. Therefore, the local Dutch LPG...article 2019

(author)Potential-induced degradation in n-type modules is typically associated with a surface polarization effect. This paper shows that modifications at the cell level can minimize the potential-induced degradation of modules caused by a polarization effect. As is demonstrated on n-PERT cells, the potentialinduced degradation can be reduced...article 2019

(author)An important reason to apply coatings on wood is to protect wood against moisture. As a result of regulations and ecological concerns, there has been a shift towards waterborne coatings, which make coatings intrinsically more sensitive to water. As a consequence of the higher sensitivity to water, the durability of both wood and coatings can be...article 2018
